Introduction:
Cetirizine is a second-generation H1 histamine receptor antagonist that is commonly used for symptomatic relief of hay fever and other allergies and can be combined with pseudoephedrine hydrochloride, a decongestant. The most common adverse effects include headache, nausea, nasopharyngitis, vomiting, and coughing.
Objective:
To report on an adolescent 18-year-old woman who developed delusional thinking and depression after starting treatment with cetirizine.
Case Report:
We report on an adolescent 18-year-old woman who developed delusional thinking and depression after starting treatment with cetirizine. Once cetirizine was discontinued, the patient returned to her clinical baseline.
Conclusions:
Physicians need to be aware of the potential psychiatric adverse effects associated with cetirizine.
